The effects of orally presented storybook models on children's cognitive achievement behavior were assessed in two experiments. Experiment I involved 100 preschool-age children who were given one exposure to either a story depicting achievement behaviors by a male/female model, or a control story describing no achievement behavior. Subjects then were asked to perform a related achievement task. No significant modeling effects were found, but a significant relationship existed between the children's recall of the story content and their performance on the subsequent task. Experiment 11 employed 60 preschool-age children who were given repeated exposures (3 to 4) to, and group discussion of, the same achievement stories or non-achievement control story. A significant relationship was observed between type of story and type of solutions to the subsequent achievement task. These findings are discussed in the context of modeling theory, with practical implications. 相似文献

This essay reviews the contribution of Rowhea Elmesky in this volume, to the field of research in science education, and places
it in the context of the juncture of youth disengagement with science, multicultural education and globalisation, with an
underlay of a historical context and critiques of science education from feminist and postcolonial perspectives. 相似文献

Alphabetic orthographies vary in the (in)consistency of the relations between spelling and sound patterns. In transparent orthographies, like Italian, the pronunciation can be predicted from the spelling, in contrast to opaque orthographies such as English, where spelling–sound correspondences are often inconsistent. The pronunciation of English vowel letters is in particular very ambiguous. In this paper, we provide a cross-linguistic investigation of orthographic transparency at the word-initial letter–phoneme level, resulting in ranked metrics for the seven languages investigated- Dutch, English, French, German, Hungarian, Italian, and Portuguese, expressed as entropy values. We focus on the contributions of vowels and consonants towards the overall orthographic transparency and provide evidence that deviations from consistent word-initial 1:1 mappings between letters and phonemes influence reaction times in naming tasks. Implications for theories of visual word recognition and speech production will be discussed. 相似文献

Although children can use social categories to intelligently select informants, children's preference for in‐group informants has not been consistently demonstrated across age and context. This research clarifies the extent to which children use social categories to guide learning by presenting participants with a live or video‐recorded action demonstration by a linguistic in‐group and/or out‐group model. Participants’ (N = 104) propensity to imitate these actions was assessed. Nineteen‐month‐olds did not selectively imitate the actions of the in‐group model in live contexts, though in‐group preferences were found after watching the demonstration on video. Three‐year‐olds selectively imitated the actions demonstrated by the in‐group member regardless of context. These results indicate that in‐group preferences have a more nuanced effect on social learning than previous research has indicated. 相似文献

This paper describes the youth culture of hostility produced by low-income and working-class African-American and White students in two urban public high schools. High school seniors were observed during the school day and participated in interviews where they described criminal activities, racism, sexual harassment, and other student hostilities taking place in corridors and classrooms. Poststructural data analysis revealed that what appeared to be senseless acts of violence were shifting adaptations rooted in prevailing discourses of money, respect, and difference. Hostilities were among the many discourse-driven adaptive strategies constructed by urban youths in school sites situated in hostile socioeconomic conditions. 相似文献

This article sheds light on an understudied aspect of the transition from school to work: the choice of a training company. It presents findings from qualitative interviews with 69 secondary school students and apprentices from the German states of Berlin and Brandenburg, focusing on their reasons to choose a training company in the dual system. What reasons lead students and apprentices to choose a training company? The most common reason is personal impressions, which future apprentices obtain in their initial, personal encounters with a company and its staff. Students and apprentices often consider location, working atmosphere and soundness. Due to this study’s regional scope, its findings may not be fully generalisable on a national or international level. However, its findings may instigate further research in countries where people pursuing certain types of apprenticeship training have to apply to companies (e.g. Great Britain, Switzerland and Australia). 相似文献

This contribution sketches the museum landscape and investigates – from different perspectives – to what extent museums can be defined and studied as an informal learning location. We shall start with a look at the heterogeneity of museums, which is a consequence of the different collections, the characteristics of visitors and their motives for visiting, and the relatively young history of didactic methods used in museums. Does learning take place? Research on visitors, which looks at this question, typically reflects in its theories of learning the paradigm shift from behaviourism to cognitive and constructivistic concepts with a corresponding change of perspective regarding the subject of investigation: whilst first investigations looked at the characteristic of exhibits and made recommendations on this basis for improved didactics, more recent studies look at visitors’ theoretic constructs of these characteristics. This article argues for a link between both perspectives in order to achieve further theoretical and practical insights. 相似文献

This investigation examined the effect of beetroot juice (BR) supplementation, a source of dietary nitrate (NO3?), on cycling time-trial (TT) performance and thermoregulation in the heat. In a double-blind, repeated-measures design, 12 male cyclists (age 26.6 ± 4.4 years, VO2peak 65.8 ± 5.5 mL.kg?1.min?1) completed four cycling TTs (14 kJ.kg?1) in hot (35°C, 48% relative humidity) and euthermic (21°C, 52%) conditions, following 3 days supplementation with BR (6.5 mmol NO3? for 2 days and 13 mmol NO3? on the final day), or NO3–depleted placebo (PLA). Salivary NO3? and nitrite, core (Tc) and mean skin temperature (Tsk) were measured. Salivary NO3? and nitrite increased significantly post-BR supplementation (p < 0.001). Average TT completion time (mm:ss) in hot conditions was 56:50 ± 05:08 with BR, compared with 58:30 ± 04:48 with PLA (p = 0.178). In euthermic conditions, average completion time was 53:09 ± 04:35 with BR, compared with 54:01 ± 04:05 with PLA (p = 0.380). The TT performance decreased (p < 0.001), and Tc (p < 0.001) and Tsk (p < 0.001) were higher in hot compared with euthermic conditions. In summary, BR supplementation has no significant effect on cycling TT performance in the heat. 相似文献

In theory, practical work is an established part of university-level chemistry courses. However, mainly due to budget constraints, large class size, time constraints and inadequate teacher preparations, practical activities are frequently left out from chemistry classroom instruction in most developing countries. Small-scale chemistry (SSC) experimentation in which one uses miniature chemical equipment can drastically reduce quantities of chemicals used during experimentation, which can help overcome some of the barriers preventing practical work in the chemistry classroom. This study evaluated the effectiveness of using miniature chemical equipment at the undergraduate level in increasing students’ understanding of chemistry concepts as well as in improving their attitude towards chemistry practical work. Two comparable groups of first-year students who enrolled for a Practical General Chemistry course participated. A quasi-experimental design was employed in which the experimental group (N = 49) used the SSC approach while the control group (N = 52) followed the traditional approach for over 8 weeks. Data were gathered using chemistry tests, attitude and perception questionnaires and interviews. Findings showed that the SSC approach was as effective as the traditional laboratory approach in improving students’ attitude towards practical work, but more effective in enhancing students’ understanding of chemistry concepts. More interestingly, SSC was positively accepted by both students and instructors as an effective strategy for teaching first-year undergraduate chemistry practicals. Some shortcomings of the approach were also identified. 相似文献
